Upgrading and Migrating
Stay updated with latest features and functionalities by upgrading HCL DevOps Deploy (Deploy) server, agents, and relays. This section also provides instruction on how to migrate your Deploy instance.
- Testing an upgrade
  Before you upgrade your production HCL DevOps Deploy (Deploy) server, for best results, perform a test upgrade, verify the challenges you are facing, and resolve them before performing an actual upgrade.
- Upgrading the server
  You can upgrade the HCL DevOps Deploy (Deploy) server to incorporate to a later version. Always upgrade agents, and agent relays in addition to upgrading the server. Upgrading the server, agents, and agent relays are each completed independently. Unless specified, upgrade the server before you upgrade the agents.
- Upgrading high-availability installations
  All servers that are configured for the HA feature must be on the same version. Thus, all servers must be upgraded at the same time.
- Upgrading agents
  In most cases, you upgrade agents from the server interface, but you can also upgrade the agents from the command line. Always upgrade agents and agent relays in addition to upgrading the server.
- Upgrading agent relays
  In most cases, you upgrade agents relays from the command line, but starting from 7.0.4.2 version, you can upgrade the server from the interface. Always upgrade agents and agent relays in addition to upgrading the server.
- Migrating the server database
  The server installation files include a script that migrates the server database from Derby to another database system. You can not migrate from any database other than Derby.
- Migrating the server to Kubernetes/Openshift
  You can migrate your HCL DevOps Deploy (Deploy) server from an on-premises production installation to a containerized instance that runs in a Kubernetes or Openshift cluster.
- Migrating an existing IBM® installation to HCL
